Being pretty new to the world of ADRs, I did a lot of reading on the boards when planning my trip. Over and over I saw people asking if they should take the DDP or TiW, with the advice always being that it depends on how you like to eat.
While I agree with that advice, I thought it might be helpful to some people if I ran thought a few numbers to see how this trip with TiW compared to the DDP. I have excluded Victoria & Albert's from this analysis, since it will no longer be eligible for TiW later this year.
If I had taken the regular DDP I would have had 9 TS credits, 9 CS credits, and 9 snack credits. While the refillable mug is also a perk of the dining plan, it doesn't have any value for me as I don't drink pop. The cost of the DDP was $60.04 per day x 9 = $540.36
Excluding V&A's, I ate 16 TS credits, 6 CS credits & 11 snacks. I went through all of the meals and calculated the cost for items covered by DDP assuming 1 entree+ 1 dessert + 1 nonalcoholic beverage or 1 breakfast entree + beverage (excluding tax & tip) for these meals and it was $521.08, or just slightly $20 cheaper than 9/9/9 credits I would have had under the DDP.
In addition, I had $245.94 in food expenses not covered by the DDP, including appetizers, alcohol, Tea @ Grand Floridian, Lunch at AMC Fork & Screen, and Spice Road Table. My worst value towards the dining plan was California Grill- it would have cost me 2 table service credits, but since I only ordered Sushi, I counted 1 sushi order towards the DDP as an entree and the remainder OOP, leading to $50 in OOP costs for that meal.
To contrast, items not covered by TiW included some snacks, some CS meals, Lunch at AMC Fork & Screen, and Spice Road Table. Food items not covered by TiW totaled $124.52.
Based on how I ate on this trip, TiW was the clear winner. I was able to get more TS for less money than if I had paid for the DDP, and more of my food choices were eligible for TiW discount than DDP. This was not a free dining period, so I don't know how DDP +OOP at rack rate would have compared with room-only discount + TiW.
If there's anything wrong with these calculations, please let me know.
